For every 1 litre of water used to make a medicine, 400 ml of sucrose and 300 ml of saline solution are used. express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

10 : 4 : 3

Step-by-step explanation:

According to the question,

For a medicine,

Water used = 1 liter = 1000 ml

Sucrose used = 400 ml

And, Saline used = 300 ml

Thus, the ratio of water, sucrose and saline water for making a medicine,

= 1000 : 400 : 300

= 10 : 4 : 3

Which is the required simplest form of the ratio of water, sucrose and saline water.

the answer is b.)
